VESTAVIA HILLS, Alabama - A Vestavia Hills toddler remains in critical condition today after he nearly drowned in a swimming pool at his home Sunday afternoon.

Brooks Boyles, 20 months, was pulled from the family pool about 2 p.m. in the 2800 block of Vestavia Forest Place. He was not breathing, and didn't have a pulse when rescue workers arrived on the scene, authorities said.

Vestavia Hills police Sgt. Steve Gurley said the boy may have been playing next to the water when he fell in to the pool. He was under adult supervision - his mother and another woman were home - at the time of the accident, police said.

Authorities said they don't know how long Brooks was in the water before he was found. "It could have been 30 seconds to a couple of minutes,'' he said. "They found him, pulled him out, started CPR and dialed 911."

The boy's mother performed the CPR until rescue workers arrived. Rescue workers were able to get a pulse en route to Children's of Alabama.

Gurley said it's his understanding Brooks is improving. "We're going to keep checking on him,'' Gurley said. "They're residents of our city and everybody is concerned about the little guy."
